1.	Two particles of masses 1.0 Kg and 2.0 Kg are placed at a seperation of 50 cm. Assuming that only gravitational forces acting on the particles mutually, the initial acceleration of the first particle.
Answer» Solution :Gravitational force between the two particles `F=(Gm_1m_2)/r^2` `F=(6.67xx10^(-11) XX 1xx2)/(0.5)^2 = 5.3xx10^(-10)`N The acceleration of 1.0 Kg PARTICLE is `a_1=F/m_1=(5.3xx10^(-10))/1=5.3xx10^(-10) m//s^2` It is towards the 2.0 kg particle.
